Memory allocation is time cost. Either user code should compare that for 
the zero bytes it should not call a GetMem or GetMem can compare this 
for user. Since GetMem already has a condition which compares for 0 - it 
is be the best place for doing this.

Therefore FPC GetMem is not only incompatible with delphi GetMem but 
also can slowdown an application if it relies on GetMem logic and does 
not have a special checks for Count = 0 case.
